考虑存在随时间变化的电场梯度和磁场时的穆斯堡尔线形状。处理两个特定的可溶随机模型：（1）具有随机波动磁场的静电场梯度，其取值+ h 和− h，每个值沿着场梯度的轴定向，以及（2）如（1）中，但波动磁场垂直于场梯度的轴。示例（2）比（1）更复杂，因为在这种情况下，波动场能够诱导核能级之间的跃迁，而在（1）中这是不可能的。对这两种情况的具体计算说明了它们之间的差异。
The Mössbauer line shape in the presence of time-dependent electric field gradients and magnetic fields is considered. Two specific soluble stochastic models are treated:(1) a static electric field gradient with a randomly fluctuating magnetic field which takes on values+ h and− h, each directed along the axis of the field gradient, and (2) as in (1), but with the fluctuating magnetic field perpendicular to the axis of the field gradient. Example (2) is more complex than (1), since the fluctuating field is in this case capable of inducing transitions between the nuclear levels, while in (1) this is not possible. Specific calculations for the two cases illustrate the differences between them.
